Hi,

Thanks for your reply. Actually the tags i mentioned are fixed in position but nobody knows when they might change the position for future requirements. So i want to fetch based on the {2:I tag only.

Thanks.

NOTMUCH-TAG(1)						      General Commands Manual						    NOTMUCH-TAG(1)

NAME

       notmuch-tag - Add/remove tags for all messages matching the search terms.

SYNOPSIS

       notmuch tag +<tag>|-<tag> [...] [--] <search-term>...

DESCRIPTION

       Add/remove tags for all messages matching the search terms.

       See notmuch-search-terms(7) for details of the supported syntax for <search-terms>.

       Tags prefixed by '+' are added while those prefixed by '-' are removed. For each message, tag removal is performed before tag addition.

       The  beginning  of  <search-terms>  is recognized by the first argument that begins with neither '+' nor '-'. Support for an initial search
       term beginning with '+' or '-' is provided by allowing the user to specify a "--" argument to separate the tags from the search terms.

       notmuch tag updates the maildir flags according to tag changes if the maildir.synchronize_flags configuration option is enabled.  See  not-
       much-config(1) for details.
